IMPROVEMENT IN MODES 0F ADJUSTING BANDS ON HAND SPINNING-MACHINES;

Specification forming part of Letters Patent No. 47,685, dated May 9,1865.

To all whom 'it may concern Be it known that I, DAVID B. (DETER, ofV

Batavia Station, in the county of Jefferson and State of Iowa, haveinvented a new and useful Improvement in Adjustingthe Bands on a HandSpinning-Machine; and I do hereby declare that the following is a fulland eX- act description thereof, reference being had to the accompanyingdrawings and the letters of reference marked thereon. v

The nature of my invenwtion consists in providing each of the uprightsholding the two pulleys M and L at the end of the track with a screw, H,to pass through the rails-of said track, and nuts K and K to fasten-saidscrews, thereby allowing the pulleys to be adjusted to givethe'necessary tension to the operating-` bands. I also widen the groovein pulley T, and severthe band O and fasten the two ends thus severed inthe groove of said pulley with twosmall wooden pins. I then passthe'other ends of band O around the pulley T, in opposite directions asufficient number of times to give the required length of run to thecar, then over the` pulleys F and L, as shown in Figs. 1 and 2, andfasten them to the carin the usual manner.

To enable others skilled in the art to make use of my invention, I willproceed to describe its construction and operation.

I construct my handspinning machine substantially in the followingmannerthat is to say, I take two pine rails; these I put together withthree turned cross-ties, so as to `form a track for the car carrying thespindle, Sto., as seen in Fig. 2. I then set this frame upon four legs,as seen in Fig. l. I thenmake a wheel and place it on said frame at itsrear end, as shown in Fig. l, as wheel E. To the axle of said wheel E Iattach crank X. I then fasten rmly to the crosstie, im mediately infront of wheel E on said track, the uprights holding the pulleys S andF, as seen in Fig. l. Y n

Pulley T is three and one-half inches in diameter and one and one-halfinch thick. It is placed between the main rails, forming the track overthe end of treadle N, as in Fig. l. Its construction is more fully seenin Fig. 3.

I turn two wooden screws, H and H, one inch in diameter with heads twoinches in di ameter. These I fasten to the end of the track by nuts Kand K. To the heads of these screws I fasten the uprights carrying thepulleys L and M, as seen in Figs. l and 2.'

Treadle N is made of three pieces, framed together so as to reach fromleg to leg under wheel E, the long piece (four feet eight inches)reaching from the legs to pulley T, the short piece, (two feet long,)with a crosspiece to hold it together, and awire, which constitutes itsaxis or center of motion, running through the treadleinto the legs. (SeeFigs. l and 2.)

The car carrying the spindle and head is provided with wheels fortraversing the track, and is framed twelve inches long, two inches high,four and one-halt inches outside, and two and one-half inches inside. Tothe front of this car, by means of an iron prong three inches high, Ifasten the spindle, and near the other end ot' the car I fasten a head,R, five inches in diameter, and place the car upon the track. (See Figs.1 and 2.) y

There are three cord-bands. The endless band P passes over wheel E, thenunder pulley S, then once around the whirl'on the head It, then` overthe pulley M, and then back under wheel E. (See Fig. l.) The course ofband O is fully set forth hereinafter. The end less band z passes aroundthe head R, and around the pulley on the spindle for giving motion tothe latter. The pulley T is turned backward by a cord fastened to itsaxle and to the end of treadle N.

In the class of machines upon whichl mine is an improvement the uprightscontaining the pulleys L and M are Xed and immovable, being attachedrmly to a solid cross beam between the rails of said track, aud band Ois passed once around pulley T, so that when you attempted to operatethe machine, if the band O was a little slack, it would slip on thepulley T, and of course the car would not move. it would bind where itpasses around the whirl of the head R until the whole machine would beat nearly a dead lock.7 Now, in order to remedy these evils, I turn twoscrews, H and Hone inch in diameter and of sufficient length to passthrough the rails of the track and receive nuts K and K. (See Fig. 4.) Imake `the heads of these screws sufiiciently large to receive theuprights which carry the pulleys L and M and hold them flrmly there- Ifthe band I is a little too taut,

,of adj ustin gbands.

The manner ot' arranging the band O on the pulley T is fully illustratedin Fig. and

, marked Enlarged plan of pulley.77

Now, the mode ot operation is this: When the machine is ready for use.as seen in Fig. 1, and marked side view,7 if the bands O or P, or bothof them are either slack or taut, by slight turn of nut K you loosenscrew H, so that you can adjust pulley L or M, or both of them, toproduce the required tension of the band (r bands. Now, by aturn of thelarge wheel E, the car is run back and the end of treadle N is elevated,then by placing your foot on said treadle, the car carrying the Thesescrews are passed 4through the rails so as to leave the heads andspindle is thrown forward to the endof the track and held there untilyou give the larg wheel a turn, which twists the yarn 5 then removingthe foot from the treadle by another turn of the wheel the car is againrun back, at the; same time taking up the thread on the spindle. Mymethod of adjusting said bandsl tends'to produce and assists in keepingup a certain easy and uniform operation ot' said machine.

Now, what I claim as my invention, and desired to secure by LettersPatent, is-

The method of adjusting bands in spinningmachines by means of screws and1'1u-ts,in combination with the manner of attaching the band to thepulley T, as and for the purposes described.
